I have what appears to be a very old brass lamp.
It has a slab of marble(?) at the base.
It has a removable white cap that sits on top of the light globe, which has the words CLM Type C Patent Pend ESLMP on it.
The cord has the letters CLM on it. The cord is mended with tape near the plug. It is also cracked at the area where it goes into the lamp.
It has a company tag on it that says Stadler-Newirth Inc. Below that is a triangle and what appears to be a long rod with a propeller type item on the end. Under that is the word Lamps.
It weighs approximately 3 - 5 lbs.
